Apps using passkeys, including TikTok, cannot access or process any of the biometric data used in the authentication process on iOS devices, and all biometric authentication data remains on users' devices. To log in, users initiate the key pairing by verifying their identity with their Apple Face or Touch ID. Passkey authentication works by using public-private key cryptography techniques. For your TikTok account, you will now have the option to use passkeys instead of a password to sign into your TikTok account directly from your iCloud account across devices. If you are an iOS user, you may already use passkeys on other applications. When you use passkeys, all biometric authentication data remains on your device and cannot be accessed or processed by third party apps, like TikTok. Passkeys are password replacements that can confirm your identity based on encrypted biometric authentication methods already available on your device.

As a part of this passkey launch, we are also proud to announce our membership in the FIDO Alliance, an open industry organization whose mission is to develop and promote authentication standards that help reduce reliance on traditional passwords which could be lost or stolen. Today, we're pleased to announce that TikTok is introducing passkeys for iOS devices - a faster, easier, and more secure way for people to sign into their TikTok accounts across their devices by using Face or Touch ID.

At TikTok, we are always looking to provide innovative ways for our community to secure their accounts and #BeCyberSmart.
